Improvement in tubular wells

Letters Patent No. 94,727, dated September 14, 1869.

IMPROVMENT IN TUBULAR WELLS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it 'may concern:

Be`it known that I, JACOB EDSON, of Boston, in the county of Suffolk, and State of Massachusetts, have invented certain new and useful Improvements in Tubular Wells; and I do hereby declare that 4the following is a full and exact description thereof', reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to tubular wells, and

. It consists of the parts constructed in the manner hereinafter described and claimed.

To enable others skilled in the art to make and use my invention, 'I will proceed to describe its construction and-use.

In the drawings- Figure 1 represents an elevation of my tubular well.

ligure 2 is a ,longitudinal section of the same.

Figure 3 represents a plan of the part H of the upper box.

' Figure 4 is' a plan of the under side ofthe same.

Figures 5 and 6 are plans of the part G of the upper box.

Figure 7 is a plan and section to ill'ustrate the construction of the strainer.

Figure 8 is a cross-section, showing theA shape -of the wire after it has been nicked.

A is the tube, of indefinite length, made of any suitable material.

Bis the strainer, made as follows, N, ig.2, being a metallic core, the low'er end terminating in a point, C, while the upper end i'sconnected by some suitable device to the lower end ot' the'tube:

The core N is perforated longitudinally by the chamber c c, iig. 2.

The section of the core is represented by :o and 1 iig. 2, it being provided with pyramidal sinkages o 'u t t, which terminate in openings s s, leadingv into the longitudinal chamber c c.

Around this core a wire, nicked as represented in figs` 7 and S, is Wound, each turn of the wire fitting closely, so that the' nicks made inthe wire form perforations, through which water may pass.

If considered desirable, the wire may be pressed, in

'the process of nicking, into the form represented in ig. 8, so that in its downward progress it will have a tendency to throw off the dirt, and thus prevent lthe small perforations formed by the nicks from being, stopped. By giving the wire the form represented in iig.'8, the pelforations are smallest at their outer surface. 4

M, iig. 2, is the lower box, provided with a suitable valve, and with a point, K', extending upward from it. The lower end of the up'pervalve H G is provided with a countersink, K, so that when it is desirable to push the lower box into position, the upper box may be used for that purpose.A The point K', fitting into the countersn'nlr K, serves to keep the lower box vertical while'being pushed down the pipe. l The packing R, surrounding the part G of the upper valve, is formed, as shown in fig. 2, so that a part votit is seized and held between G and H.

The part H of the upper valve screws upon the piston F, but the pa-rt GrA slips freely over-it, and is held by a set-nut, W, fig. 2.. y

The 'part H is provided with a number of nicks, L L L", iig. 3, into which corresponding ribs, l l l, are made on the lower side of G, fig. 5, so that when the parts of the upper valve G andHare put together, one'cannot turn without the. other.

I form the air-chamber of my pump byi'orming the cap D substantially as shown in tig. 2, and attac-hing to the inner pox tion O O the pipe P, thus leaving thel space Q Q, between the pipe P and the outer walls,'as an air-chamber.

T, figs. 1 and 2, is the discharge-nozzle.

W Z, fig. 1, is a small cock, leading from the tube A, to allow the water within thetnbe to run out, and thus avoid the danger of freezing.-

The construction of the cock W Z, shown'in section at Z', Figure 1", is novel. The lower end of Z terminates in a hollow screw, p p, Ywhich lits into W', this screw p p heilig provided with an orifice, n o, so that if it is screwed hard down against'the top-of W',

-no water can escape; but it' it is partly unscrewed, so

that the orifice o will he above the top of the pipe W', then the water can pass freely through a o.

W is a stem, reaching from the cock Z to the surface of the ground, by means of vwhich it may be closed on shut.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A strainer, when made by winding wirearound a channelled or corrugated supporting-core, said wire being nicked, as hereindcscribed and shown.

2. The core N of the strainer, when the core has a central chamber, and is provided with alternating pyramidal recesses, communicating with said chamber, in the manner arrangedvand described.

3. The point K', projecting upward from the lower box, when said point acts, in conjunction with the countersink K, for adjusting and forcing the lower box into place, as herein described and shown.

4. Constructing the upper box of twoparts, Gr and H, when said parts are arranged in the manner herein described, and for thepurpose setrforth.

JACOB EDSON.
